Also, the rad levels are insane and you'll need to suit up and hotkey RadAway. There are a few items near this inaccessible entrance, but nothing of importance. I used Dogmeat to retrieve some of them, as the radiation doesn't seem to bother him.
As for the towers you can activate; once you've activated one, explore a little until you find see a drainage chamber entrance. If you can't spot it, using the local map on your Pipboy might reveal the entrance. There might be something useful down there, it varies.
